LEATHER CUTTER(4 Appncationelea December as, reas. sei-iai No. 156,638(Vv y.

This invention relates to new and useful improvements in leather cutters, and has for its primary object to provide a highly novel,

- simple, and eiiicient device whereby leather may be properly cut without requiring'the use of a complicated power driven machine.

The invention further aims to provide ya leather cutter wherein'- the same may be regulated for cutting leather of various i0 thicknesses.k Y a l With the foregoing and other objects in view as the nature of the invention willbe better understood, the same comprises the novel form, combination and arrangement of parts hereinafter more fully described, shown in the accompanying drawing and claimed.

In the drawing wherein likey reference characters indicate vcorresponding parts throughout the several Views:

Figure 1 is a longitudinal section of a leather cutter constructed in accordance with the present invention.

Figure 2 is a detail vertical section taken through the cutting end thereof substantially upon the line 2-2 of Figure 1, and looking toward the direction of the arrows.

Now having particular reference to the drawing, my novel leather cutter consists of a vertical standard 5, having a suitable base 6 at its lower end to facilitate the anchoring of the cutter to a work bench or other suitable support. At the upper end of this standard 5 there is formed a pair of vertically spaced horizontally extending 'and parallel hollow shaft guides 7 and 8 that are open at their opposite ends as clearly indicated in Figure 1.

Mounted within the ends ofthe lower,

guide 8 are bearings 9-9 while arranged longitudinally within this guide is a! shaft 10, the ends thereof being of increased diameter for fitting relation within said bearings as disclosed. Upon the inner end of this shaft 10 is a large gear 11, while upon the tachably disposed a milled leather feed roller 12 formed circumferentially with a V-groove 13 for a purpose to be hereinafter more fully described. To facilitate the turning of this shaft 10 there is provided a hand crank 14 attached to the eXtreme inner end of the shaft upon which is mounted the gear 11. f

The bore lwithin the upper shaft guide 7 is considerably greater than the bore in the p l5 lower guide, ywhile within the bottom of this guide adjacent the opposite ends there# opposite projecting end of the shaft is de-or r13 in the feed roller'12.

of are sockets 15 `and 16 within which are y `slidable`the'lower ends of bearing blocks 15 and 16 that are formed with longitudinall and registering sliaft 'receiving bores. Vit-hin the'guide 7 is a" shaft 17, the' ends thereof being of reduced diameter and being mounted within thefbores of the bearing`E blocks 15',A and 11G respectively. Pivoted vwithin the bore` of said guide'7 beneath 'the shaft 17 isan elongated lever 18 the forward end of `which is arranged within a longitudinal slot 19 in the bottom of the bearing block 15. Arranged between this lever. 18 and the bottom ofthe bore of said shaft guide 7 is an expansiblev coil spiing`20, for the purpose of normally swingingthe'outer end of 'the lever 18 upwardly for, conseupward direction. Arranged within the `socket 16 for the bearing block 16 and benv quently'forcing said bearing block 15f in an ranged within these bearing blocks, saidy v it is necessary to state that the teeth of these i gears are ofsuch a length as to permit the upward movement of the shaft 17 together with the gear 22 to the position disclosed in Figure 1 without the teeth becoming out of mesh.

Threaded within openings in the upper shaft guide 7 directly above the bearing' blocks 15 and 16 are wing headed set screws 23-28, which when turned inwardly will force the bearing blocks in a downward direction against the action of the springs 20 and 21 for a purpose shortly to be described;

The forward reduced end of the shaft 17 extends beyond the shaft guide 7 and is equipped at said projecting end with a removable circular cutter blade 24; in vertical alignment with the circumferential channel Obviously, by adjusting the position of the shaft 17 within the guide 7 leather strips `of various thicknesses may be properly cut or may be slit as desiredi l AThere may be, and preferably is mounted above thel cutter 24:` a hood 25 detachably connected to the outer end of the shaft guide 7, this hood being obviously for the purpose of protecting the operator 'from the cutting hlade Qt.

In view of the foregoing` description when considered in conjunction with the accompartyingr drawing. it Will at once he apparent that I have. provided a hilahlbv novel, simple, and etlicicnt. leather cutter that is well adapted for all the purposes heretofore designated, eren though l, have herein ,shown and described the invention as consisting ot certain detail structural elements it. is nevertheless to he understood that some changes may he made therein withoutel'eeting the spirit and scope ot' the appended claim.

Having,r thus, described the invention, what I claim is In a cutting;` machine of the class described, a vertical standard, a pair of elongated hollow guide arms arranged horizon tally in Superposed relation on the standard, the bore 0l' the upper guide arm heilig greater than the bore ot the lower guide arm, bearings arranged in the hores Ot the arms at the ends thereof, the bearings asso eiated with the upper guide arm being adapted for vertical slidalile moreu'ient. therein, a sha'lft extending longitudinally through each bore and journalcd lor rotation in the respective pairs of heariir means for rotating the shaft simultaneous y, a. leed roller upon the outer end ot' the lower sha-lit, a cutter on the outer end ol,l the upper shaft, resilient means cooperatingA with the slidalile hearings for normalltv tugging` the outer carnringr shaft: away tron] the feed roller carrying shalt, said re1v=ilient means includingr an elongated lever pirot'cd at its inner end within the hore ot the upper arm below the shaft, the lu?arin; r in the upper arm adjacent the outer end tliereotl liciinir formed with a slotin the lon'er portion there of, the outer end of said lever lieingiI disposed in said slot and engaging said hearing, an expansible coil spring interposed lietu'eei'i the intermediate portion of the lever and the lower portion of the upper guide arm, and manually operable means for moving the upper shalt downwardly toward the lot-rer shalt wherel'iy the space between the f -uttt-r and the feed roller may he adjusted.

ln testimony whereof I allix my signature.
